With the exception of the dump dated 06/04/16 all of the others point towards Cubase and MOTU (Mark of the Unicorn) the dump dated 06/04/16 points towards PaeFireStudio.sys which is Presonus Fire Studio software and at the same time the MOTU drivers failed to load, as MOTU is implicated in both scenarios I suggest that you check this first.
